DESCRIPTION
The audiotest utility runs a test for the named audio device (or all
audio devices found on the system if none is given). The test includes
playing an audio sample over each channel and measuring the rate of
playback for clock drift.
OPTIONS
The following options are supported:
-1 Loop mode. The test is run in an infinite loop.
-2 Stereo (2-channel) mode. This is the default mode. Playback
assumes 2 channels are present.
-4 Quadraphonic mode (4-channel surround). The test assumes that
four surround channels are present.
-5 Surround sound mode (5.1). The test checks the left, right, sur‐
round left, surround right, and center channels. The low fre‐
quency effects channel is not tested.
-7 Surround sound mode (7.1). The test checks the left, right, sur‐
round left, surround right, back surround left, back surround
right, and center channels. The low frequency effects channel is
not tested.
